WINDING-MACHINE.

Specification of Iietters Patent. Applicationfiled May 18, 1911. Serial No. 6 27,987.

To all whom it may concern:

Be it known that I, J AKOB VIVBYAUNEER, a citizen of the Republic. of Switzerland, residing at Erlenbach, Switzerland,

have invented newand useful Improvements in Winding-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as--will enable others skilled. in 'the artto l0 which-it-appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Machines for the parallel-winding of bobbins have already been constructed, in

, which, for the purpose of insuring-better bindin of the thread with the bobbin-body, and o attaining a more slim or pointed form, a camis employed having the shape of athree-cornered heart. Thiscam causes all the bobbin-spindles to rise orfall simultaneously and vt-heth're'ad is coiled upon the bobbin by a rotary threadtguide. The three corners of the cam are of different heights and its recesses of difi'erent depths, the.

. arrangement being such that the spindles are sunk todifierent extents, so that individual thread-layers will be beyond fthepreceding ones, and with that part which is nearest to the bobbin-body lying on the latter. The drawback of such winding-mm chines isthat the bobbins do not receive the same number of turns in every thread-layer, so that the individual thread layers lying beyond the preceding ones, do not ,'in the case of all the bobbins, lie on the bobbinbody with that part which is nearest to the.

guide execute a rotary motion, and one of latter. The consequence is that the winding of the bobbin is not uniform. The reason of this is that all the'spindles are raised and lowered in common by a single cam, and that the'thread-guides are rotated independently of the axial motionof the spindles by mechanism provided -for each spindlesepa': rately.

The presentlinven tion relates. to improve ments in Winding-machins,- whereby the above mentioned defect can be overcome, and it has reference to'those winding-machines in which the spindle and the'thread- SoHliRER-NUss- Patented Aug. 15, 1911.

them is'revolvcd with positive motion by cam, having the form of a toothed wheel;

with'symmetrical halves, and is time slid axially.

' The main feature of the invention is that a second rotary lifting-device is provided, positively actuated-by the said cam, which device on rotating imparts a sliding 'motion to the sa'id'cam, and thus an extra sliding motion 'to the spindle or the threadat: the same guide (after the same has made a certain".

number of revolutions.) In this manner the bobbin is uniformly wound, therebeingthe same number'of turns in each thread-layer,-

and individualthread-layers lie beyond the preceding ones, with that part which isnearest to the bobbin-body lying on the latter, for the purpose of insuring better bindmg.

- One embodiment of the invention is illustrated in the accompanying drawing, in

which it is shown applied to a bobbin Winding-machine for cross-winding. v

' Figure-1 is an elevation and part section, Fig. 2 shows a detail, being a cross-section on the line A'A of Fig. '1, Fig.3 shows certain thread-layers wound by a machine (if the .well known construction already referred to, Fig.4 is a similar view of threadlayers wound according to the present invention.

- p 1 designates the spindle, carrying the cop or bobbin 2 at the top. On this spindle there is loosely mounted a toothed sleeve 3,

to which there is secured a level friction disk 4, which supports the thread-guide 5,

togetherwith the device for vertical adjustment of the same. I Withth'e sleeve 3 there meshes a gearl6, to which there'is rigidly secured another gear 7. This latter engages with a gear 8, on whose shaft-9 there is mounted a cam 10- presenting two parallel ribs or flanges 11 and 12, 18 being the groove between the same. This groove constitutes acam-track, the ribs 11 and 12 at the one:

part lying nearer to the bottom edge of the cam, whileat the part located diametrically opposite the first said part they lie nearer. the upper edge of the cam. The cam 10 thus possesses symmetricalhalves. Therib 11 is toothed on its periphery, and with it there .rneshes a toothed sleeve 14:, fastly' mounted on the spindle 1. The sleeve 14 rests on a sliding-block 16, through which there pass the spindle 1 and a rod 15. From the block 16 there projects a pin 17 which engages in the groove 13. Below the cam 10 the spindle 1 has teeth 23 cut in 1t, with whichthere meshes va gear 19, slidably mounted on a pin 18. Mounted on this pin there is also a roller 20, and upon the latter the gear 19 rests: On its under face the gear 19 has a concentric annular cam-surface 21, which rises from the plane of the earn and descends through the same extent to thelaneagain; The shaft 9 has a collar or shoulder 22, which rests on the gear'19, so that when through rotation of the shaft 9 the gear 19 is lifted by its cam-surface 2]. contacting with the roller 20, the said shaft, together with the cam 10, is likewise raised. The ratio of transmission between toothed sleeve 23 and gear 19' is 1:3+1 tooth; that is to say, if the sleeve 23'has, for instance,

7 six teeth, the gear 19 will have nineteen During such winding the spindle 1 will at times ascend through a certain extra dis tance, since the shaft 9 at certain intervals will be more or less raised by the camfaced gear 19. Through this superascent of the spindle l, theparts of the individual thread-layers located nearest to the bobbinbody will be so (foiled upon the latter that they .do notall lie on it, but only the said part of each thirdthread-layer. Thus, for instance, if the mechanism occupies the position shown in Fig. '1, then, of the thread layer which is just being formed, that part which islocated nearest to the bottom-body will come to lie at the'point a. (Fig. 4:.)

I If the shaft 9 is turned'through one revolution, the gear 19 will make somewhat less than one third of a revolution. During such period the cam-track 21 will travel over the roller--20 to somewhat less than one half of its height, and will thus raise the shaft 9- -with' spindle 1, so that the part in question of the next thread-layer will lie at the point 0. After "the next rotation of the shaft 9 the gear 19 will again have made somewhat less than one third of a revolution, and a higher part of the cam-track 21 will now lie above the roller 20 than at the moment when the part a was being wound on; so

that the par-tin question of the next threadlayer will lie at the point e,-that 15 to say, somewhat lower than the point 0. After the third rotation of the shaft 9, the roller 20 will again lie upon the face of the gear 19, and the said part of'the next thread- I layer will come to lie at the same height as that at the point a. he procedure now repeats itself, so that each third thread- .laver, at the part which is nearest to -the bobbin-body, always projects above the like parts of the two other thread-layers. All the parts at the level of the point a lie on the bobbin-body 2.

- By the above described manner of apply-- ing the various threaddayers to the bobbin uniform winding is insured. Each threadlayer exhibits-the same number of turns, and 'thereis no liability to knot, such as occurs when the spindle makes no superascent (as in the winding depicted in Fig.

3), unless the thread is sufficiently restrained. With the presentinvention therefore, pronounced restraint of the thread is not' necessary on windin the bobbins, whence soft winding results yet the winding istightly bound to the bobbin-body so there is no danger of its slipping unto the same in the shuttle, when the latter is struck by the picker. The invention also enables the use of much thinner bobbin-bodies.

The mechanism for efiecting super-ascent of the spindle can naturally beniployed not only for machines for cross-winding (as above described), but also for machines in which the bobbins are parallel wound. It

will also-he obvious that the axial'fsliding I might be executed by the thread-guide, instead of by the-spindle, without therebeing any departure from the spiritof the present invention.

Having thus described my invention, I claim as new:

1. In a winding-machine, a rotatable bobbin-spindle, and a rotatable thread-guide, an axially slidable cam positively rotating and axially sliding the one of the said members and rotary means positively actuated by the cam and imparting to the latter in-.

termittently an. axially sliding motion,

whereby the said member which is rotated and slid by it receivesan additional axial sliding motion, substantially as and for-the purposes described.

2. In a winding-machine, a rotatable bobbin-spindle, and a rotatable thread-guide, a

toothed shaft, an axially slidable toothed I. I

camon said shaft, having symmetrical halves, positively rotating and axially sliding the one of the said members, a pin on a stationary part, a gear slidably mounted on the said pin and meshing with the shaft of the said cam, and supporting the latter, and presenting a cam-track, and a roller mounted on the said pin and engaging with track cooperates with the roller the said cam is lifted and the member which ro-' tated and slid by it consequently receives an additional "sliding motion, substantially as and for the purposes described. 1

In testimony that I claim the foregoing as iny invention, I hiire signed my'name in" presence of two subscribing Witnesses.
